Actually, I'm beginning to think that this may not be a CNC machine as the seller (who inherited it) is assuming. Instead, it may have an add-on VFD? kit which would explain why there is a Mitutoyo 2-axis DRO on it as well. Is it likely that AC variable speed motors would be added to the lead screw and cross slide screw and controlled by a VFD or even that the lathe and mill's 3/4 hp AC motors might be controlled this way as well, bearing in mind that the setup could be quite old (as far back as 92). wish I knew how to post some pics on this forum.
